Five steps involved in user interface design are: Use scenario development It depicts the outline of the steps the users perform to accomplist part of their work.It is considered to be a used path through a use case.The goal of using these is to describe the handful of most commonly occurring use scenarios so that interface can be designed to enable the most common uses to be performedd simply and easily. Interface structure design This dedfines the basic components of interface and how they work together to provide functionality to users. This diagram shows all the screens used by system and how the user moves from one to another. Interface standards design This depicts the basic design elemnts that are common across screens,user forms and reports of system. Depending on the application,there may be several sets of interface standards for diffferent parts of system. Interface design prototyping This is a mockup or simulation of a screen ,user or report.A prototype os prepared for each interface in system to show users how the system will perform.The three most common approaches used are storyboards,HTML prototypes and language prototypes. Interface evaluation This is to understand how to improve the interface design.There is no hard and fast rule which guarantees a great user interface. Most designers design an interface that meets their personal preferences. Hence, the key message is to have as many people as possible evalluate the interface.
